This device checks the authenticity of banknotes and is used in ticket machines for example. The machine draws the notes in, transports them to the checking device on the inside and outputs the product following a successful check. In order to guarantee the speed of the whole process, the developers used a pick-and-place system using compressed air. This is based on drylin® e-axles with stepper motors. Also used: the reliable e-chain® from igus®.
